"India Meteorological Department's long range forecast for the 2012 southwest monsoon season (June-September) is that the rainfall for the country as a whole is most likely to be normal. Quantitatively, monsoon season rainfall is likely to be 99 percent of the long period average (1951-2000)," said Deshmukh.

According to IMD, there is very low probability for the season's rainfall to be deficient, which is below 90 percent, or excess, which is above 110 percent.
